Article Abstract
The homochirality of biomolecules in nature, such as DNA, RNA, peptides and proteins, has played a critical role in establishing and sustaining life on Earth. This chiral bias has also given synthetic chemists the opportunity to generate molecules with inverted chirality, unlocking valuable new properties and applications. Advances in the field of chemical protein synthesis have underpinned the generation of numerous 'mirror-image' proteins (those comprised entirely of D-amino acids instead of canonical L-amino acids), which cannot be accessed using recombinant expression technologies. This Review seeks to highlight recent work on synthetic mirror-image proteins, with a focus on modern synthetic strategies that have been leveraged to access these complex biomolecules as well as their applications in protein crystallography, drug discovery and the creation of mirror-image life.

The growth of large ice crystals during freeze and thaw events is a challenge in diverse settings from transportation and agriculture to foods and biomedicine. Design, synthesis, and evaluation of antifreeze polypeptides that inhibit ice crystal growth at µg concentrations are reported herein. The polypeptides, composed of Ala and Glu, are prepared using economical methodology, are stable after thermal events, are biodegradable, and are nontoxic to human cells.

Mirror-image poly(ethylene terephthalate) (PET) plastic-degrading enzymes have emerged as promising biocatalytic platforms due to their exceptional enzymatic stability and low immunogenicity. Currently, the sole reported mirror-image plastic-degrading enzyme, the D-form of 231-residue PET hydrolase ICCG (engineered leaf-branch compost cutinase variant), suffers from thermophilic activity requirements, which limits its practical applications. Here, the first total chemical synthesis of a mirror-image 271-residue D-Fast-PETase was presented by using an enzyme-cleavable solubilizing tag strategy.

Breast cancer brain metastases (BCBM) are a significant clinical challenge, especially in aggressive subtypes like HER2-positive and triple-negative breast cancer. This review discusses hormone receptor discordance, it's existence and contributing factors, the role of the bloodbrain barrier (BBB) in metastatic progression, and therapeutic modalities. While local treatments such as surgery and radiotherapy remain foundational, advances in systemic and immunotherapeutic approaches show promising potential.

Purpose: Sutures are the most frequently utilized to ensure a watertight seal, reposition the flap to its natural alignment, provide mechanical stability to secure tissues during the early healing phase, and reduce the risk of postoperative complications. This study aimed to evaluate and compare the effectiveness of the V-Loc Poly (p-dioxanone) knotless Tissue Control Device wound closure system and conventional silk suture in intra-oral closure following surgical removal of impacted mandibular third molar.
Methods: This is a prospective randomized split-mouth study involving 17 patients with bilateral mirror image third molars, one side received V- Loc unidirectional knotless barbed sutures while the other received silk sutures for the study and control group on a week's interval accordingly.

Base excision repair (BER) is a biologically and biomedically important cellular pathway responsible for repairing common DNA lesions. As a central member of the BER pathway, apurinic/apyrimidinic endonuclease 1 (APE1) is important in DNA repair and has been identified as a diagnostic and predictive biomarker for several diseases, motivating the development of analytical methods. However, the current repertoire of APE1 probes, the majority of which are derived from nucleic acids, are poorly suited for use in living cells and organisms, putting many promising biomedical applications of APE1 out of reach.
